When Arduino debuted, most sensors and other interfacing devices ran on 5 volts. This tutorial shows how to hack your 5 volt Arduino board to run on 3.3 volts. It is a simple procedure involving ...

I've tested this code using an Arduino Nano + Level Shifter and it worked like a charm! As I want to design the smallest possible PCB so that it fits into my Fanatec QR Adapter (52mm to 70mm) I want ...

The RA4M1 I2C controller runs slower than the selected clock rate for some 3.3V devices. These devices run at the full rate on Uno R3. I have had no problems with 5V devices. All 5V devices I have ...

If you’ve ever tried connecting a 5V Arduino to a 3.3V sensor and got nothing but weird signals, this little module is here to save the day. The TXS0108E level shifter is an 8-channel, high-speed ...
